Application filed November 17, 1925.. Serial No. 69,577.

This invention relates to improvements in combined finger rings and cord cutters .of the type disclosed in my U. S Letters Patent'No.1,521,051-, granted Dec. 30, 1924.

.The main purpose of the present invention 7 is to provide a combined ring and cord cutt'er arrangement in which the cutting means will at alltimes, be concealed but is ready foroper'ation Without requiring the slipping of apatch r-move'meni of any operating member, it only being necessary to bring the piece of string or cord to be cut against the companying drawings, and set forth in the claim hereto appended, it being understood that'various changes in the form, proportion, 39 size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or. sacrificing any of the advantages of the invention.

Referring to the drawing;

Fig. 1 represents a perspective view showing the manner of usingthe ring as a cord cutter.

Fig. 2 represents atop plan view of the ring of this invention.

Fig. 3 represents a the set removed. i

Fig. 41 represents a side elevation of the ring.

Fig. 5 represents a side elevation of the ring showingthe position of the parts assumed when operating it went string or cord.

Fig. 6 represents an enlarged sectional view of the ring.

Fig. 7 represents a bottom plan view of the setting showing the cutting means applied thereto.

In carrying out the invention there is provided an ordinary ring body portion 1 hav- I ing a base 2 on its upper side. Mounted on this base is a setting 3 which, in the pres top plan view with ent instance is shown of adiamond shape. This setting 3 is in the nature of'a fiatfplate .EFF

and the ring is similar to an ordinary Signet ring. Projecting downward froln'tlie under side of and suitably fastened to the'setting 8 is a lug 4 which extends loosely into an opening 5 provided in the base 2. A hinge pinfl6 is inserted'through the base laterally and through the lug i to hingedly connect the set-tingwith'the ring, Thelug i is between the ends of the setting and to provide for holding the setting close against the base 2 at all times, an expansion helical spring 7 is mounted between the basev and setting, the ends of said spring being engaged in registering recesses 8 and9 provided inthe base and setting respectively. Certain ends or sides of the base andv setting are beveled as at 10 so as to'provide a shallow notch into which a piece of string or cord, as shown at A, may be moved. A cutting knife 11 is sef cured by fastenings 12 to the under side of the setting 3 and-is. adapt-ed to-engagei in a recessor groove 14: formed in the base 2.

The setting may have any suitablerdecora- 1 tion, for eXample,a jewel, as shown at 14.

The setting normally lies close to the outer I v side of the base sothat the spring lock and knife are entirely concealed. The ring therefore appears at all times as an ordinary ring and its ornamental value is hanced.

therefore en- To cut a piece of string or cord, .when the ring is worn upon the hand, as shown in Fig. 1, the operator brings a piece of cord against the beveled faces 10 at one end of i the ring and the pressure of the cord against the setting, causes the setting to rock on its pivot '16 and the outer end thereof to lift u wardly against the'action of the spring 'Thisraising of the setting, lifts the knife 11 out of. the groove 14 and as the cord is r 7 moved between the setting and base, it will encounter the knife and be severed. j The knife is arranged diagonally so as to produce abetter cutting action when the cord is drawn over its sharpened edge. The ring of this invention is at all times ready for the cutting operation, it beingunnecessary to operate a catch or any operating member to prepare the, cutting. mechanism for operation. When the string or cord is withdrawn, the spring 7 returns'the setting 3 to closed position, lying in close engag'eirient with the base. Heretofore' in the art it has necessarv to provide, smite insane for no i when preparing the ring for a cord cutting operation. I am also aware of cord cutting of the ring.

rings where springs maintain the setting raised so as to permit of access to the cutter, but in rings of this type, the cutting mechanism is revealed and spoils the appearance The" present invention therefore, does away with the objections which were present in rings heretofore vmade and simplifies the construction and operation of said rings, to say nothing of lessening the costof manufacture thereof.

I claim:

A combined finger ring and cord cutter comprising a ring body portion having an opening therein and provided with a groove,

the ends of which terminate short of the edges of the body. a member having a lug depending therefrom between its ends and sides and extending into said opening, a pin extending through the body portion and said .lug, said body portion and member having registering recesses therein in their opposed faces, a spring mountedin the recesses and holding the said member flat against and parallel with the body portion, a knife carried by said member and extend ing into said groove, said knifebeing nor mally concealed between the'body portion and said member, the opposed faces oft-he body portion and said member at certain corresponding edges thereof being bevelled to permit of insertion of a cord between said member and body portion;
